Volume 1 This book provides an accessible, practical and comprehensive introduction to the three gauge theories of the 'standard model' of particle physics: quantum electrodynamics (QED), quantum chromodynamics (QCD) and the electroweak theory. For each of them, the authors provide a thorough discussion of the main conceptual points; a detailed exposition of many practical calculations of physical quantities; and a comparison of these quantitative predictions with experimental results. Topic: Particle Physics
This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2633 new measurements from 689 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summarize searches for hypothetical particles such as Higgs bosons, heavy neutrinos, and supersymmetric particles. All the particle properties and search limits are listed in Summary Tables. We also give numerous tables, figures, formulae, and... Topics: Particle Physics, "
Understanding the fundamental forces of nature is one of the hallmarks of modern physics. However, mathematically describing these forces often results in the emergence of infinities. On this program, Prof. Frank Close discussed the infinity puzzle. Topics: science, cosmology, particle physics, physics, groks Source: Groks Science Radio Show Podcast
Fermi National Accelerator Lab, better known as Fermilab, has been actively searching for the elusive Higgs Boson, the particle that may give mass to the Universe. However, the clock is ticking and their time may soon be up. On this program, Clayton Brown discussed the Atom Smashers.

Detailed analyses of WMAP and Planck data can have significant implications for noncyclic pre-Big Bang approaches incorporating a new fundamental scale beyond the Planck scale and, potentially, new ultimate constituents of matter with unconventional basic properties as compared to standard particles. Cosmic-ray experiments at the highest energies can also yield relevant information. Hopefully, future studies will be able to deal with alternatives: i) to standard physics for the structure of the... Topics: Physics, Particle Physics, Cosmology, Pre-Big Bang, space-time

Trillions of subatomic particles called neutrinos are zipping through our bodies every second of every day. If that gave you goosebumps, don't worry because they're very shy and rarely interact with other matter- a property that makes them difficult to detect. Astrophysicist Dr. Ray Jayawardhana joins us today to discuss the hunt for neutrinos, the elusive elementary particle that brings news from distant stars and can help us understand the nature of antimatter. A tall order for a very small... Topics: Groks, neutrinos, Jayawardhana, groks science show, particle physics
It has not yet been elucidated whether the observed flux suppression for ultrahigh energy cosmic rays (UHECR) at energies above 4 x 10E19 eV is a signature of the Greisen-Zatsepin-Kuzmin (GZK) cutoff or a consequence of other phenomena. In both cases, violations of the standard fundamental principles of Physics can be present and play a significant role. They can in particular modify cosmic-ray interactions, propagation or acceleration at very high energy. Thus, in a long-term program, UHECR...

The BICEP2 collaboration reports a B-mode polarization of the cosmic microwave background (CMB) radiation inconsistent with the null hypothesis at a significance of > 5 sigma . This recent and potentially important result is being often interpreted as a signature of primordial gravitational waves from cosmic inflation. However, the arguments supporting such an interpretation are strictly based on standard cosmology and do not take into account possible new phenomena suggested by Planck...

Canonical Quantization: In quantum mechanics, canonical quantization is a recipe that takes us from the Hamiltonian formalism of classical dynamics to the quantum theory. The recipe tells us to take the generalized coordinates qa and their conjugate momenta pa and promote them to operators. The Poisson bracket structure of classical mechanics morphs into the structure of commutation relations between operators, so that, in units with _ = 1,...

Abstract. Is Quantum Mechanics really and ultimate principle of Physics described by a set of intrinsic exact laws? Are standard particles the ultimate constituents of matter? The two questions appear to be closely related, as a preonic structure of the physical vacuum would have an influence on the properties of quantum particles. Although the first preon models were just « quark-like » and assumed preons to be direct constituents of the conventional « elementary » particles, we suggested...

In this �rst section we will discuss various aspects of classical �elds. We will cover only the bare minimum ground necessary before turning to the quantum theory, and will return to classical �eld theory at several later stages in the course when we need to introduce new ideas.

These lectures are aimed at beginning graduate students. They assume a working knowledge of quantum �eld theory and general relativity. The lectures were given over one semester and are based broadly on Vol. 1 of the book by Joe Polchinski. I inherited the course from Michael Green whose notes were extremely useful. I also bene�ted enormously from the insightful and entertaining video lectures by Shiraz Minwalla.

At the beginning of the last chapter, we stressed that there are two very di_erent interpretations of conformal symmetry depending on whether we�re thinking of a �xed 2d background or a dynamical 2d background. In applications to statistical physics, the background is �xed and conformal symmetry is a global symmetry. In contrast, instring theory the background is dynamical. Conformal symmetry is a gauge symmetry, a remnant of di_eomorphism invariance and Weyl invariance.

The development of the statistical bootstrap model for hadrons, quarks and nuclear matter occurred during the 1960s and the 1970s in a period of exceptional theoretical creativity. And if the transition from hadrons to quarks and gluons as fundamental particles was then operated, a transition from standard particles to preons and from the standard space-time to a spinorial one may now be necessary, including related pre-Big Bang scenarios. We present here a brief historical analysis of the... Topics: Elementary Particle Physics, Cosmology, Foundations od Quantum Mechanics, Quantum Field Theory
